Suppose y varies directly as X, and Y equals 16 when x equals 8 find y when x equal 16
Korolek [52]
When
y = x \\ y = 16 \\ x = 8
you would have to use comon multiples to find what both numbers have in common, a short way of finding this would be
16 \div 8 = a
where (a) is the answer of the equation, (a) would be 2 because 8*2=16 meaning
y = 2x
